DRY BATTERY.

To all whom it may concern:

Be it known 'that lfMancos H. Morrn'r'r,

Lakewood, inthe county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in DryB atteries, of which the following is a full, clear, and exact description. I 1

This invention relates to an improvement in electric batteries and more particularly to a dry battery casing for use in electric batlamps. ne object, of my invention is to provide a rality of dry cells to form a battery suitable for use in a hand lantern.

, A further aspect of this invention consists in. an arrangement for reventin trolyte from. reaching t e metallic parts of the lantern.

Another object of my invention is the combination with -a battery having I the afore mentioned features, of a space for storing a lain bulb. I

T e invention is illustrated in the accom-' panying drawings in which 1- Figure 1' is a-top .plan view. Fig. 2 is a.

cross section on the line AA 'of Fig.1. Fig. 3 is a view artially in cross section on the End B'-B 0 Fig. 1.. Fig. 4 is a bottom "view. Fig. 5 is a partial cross sectional view through the center of a modification.

As shown in Fig.1 the battery 'consistso a plurality of dry ce1ls', .1, 2, 3"and 4, vfour being shown only by way oi'example, inclosed in a cardboard casipg'fi finished with a surface materialfi'. The cells are the well known typeconsistingof cylindrical zinc containers 7 central, carbon electrodes 8, a mix 9 therebetween. containing electrolyte,

and a seal 10 at the top. The cells maybe provided with jaclrets:which mag-also be waterproofed if desired." Each 0 i the cells 1, 2 and 3 have metallic strips 11 soldered or otherwise fastened to thezinc container. A stri 12, which serves as a terminal, is solc ered to the bottom ofthe zinc container of the cell 4, and brought out through ,a slit in the bottom of the casing. The second terminal consists of a fiat strip.13 soldered to the carbon electrode of the cell 3 and also brought out at the bottom through a slit.

To properly insulate the cells, insulating Specification of Letters Patent.

' over the ed e of the hea layer and't the ,ad acent cell. The term'in 13 cobperate .With the terminal's-of the batte to complete the circuit. Such a battery lam the elecconsiderable rough usage, and consequen i space for subjected to a very heavy current; drai which in many. cases causes the electrolytejfi to bubble or be forced'through a hole'i e seal provided for the-escape ofgas To eliminate these disadvantages.

A battery of this ty'p ,-'maybe inserte' in a metallic lantern havingan'incandscen lamp in the bottom and contacts'adapted is intended primarilyv as a railway'switch mans lantern and in this service must stain the incandescent lamp is? often brokeng storing a renewal lamp 1-9715; pro vided in the battery .by thecentral openjn formed between the cells.

Dry cells'when used inbattery lamps a electrolyte often foams on bubbles the top of the, seal and the: edge of th'QllSifiE, f and in this manner will come in contactwlt and corrode the metallic parts oftliel edge of the case above the top oft container. This'will prevent t eelect ytb and thus to a largetent willprevent bubbles from reaching th metal arts of the lantern.'

In electric batteriee, a battery case having :nbottom niemherfa plurality of cells therein having a central chamber thercbetween to store an extra lamp, a tubular incinbcr in the lower part of said chamber adapted to receive the base of the lamp, terminals extending through the bottom of the case, and a cover for the top of the case ha vinp a central hole above said cavity for inserting the lamp.

In testimony whereof, I hereunto allix my signature.
